Abstract
Many parallel applications in MPSoCs take advantage of multicast communication. Several multicast schemes such as path-based, tree-based, and unicast-based have been proposed in interconnection networks. Path-based multicast scheme has been proven to be more efficient than the other schemes in on-chip interconnection network. A new adaptive routing model based on Hamiltonian path for both the multicast and unicast traffics, called Hamiltonian Adaptive Multicast and Unicast Model (HAMUM), is presented. Results obtained in both multicast and mixed traffic models show that the proposed adaptive algorithm for multicast aspect has lower latency and power dissipation compared to previously proposed path-based multicasting algorithms with less than 0.5% hardware overhead. Additionally, for the unicast aspect the proposed adaptive model outperforms the other unicast turn models.Keywords
